Northeast Fisheries Science Center researchers are engaged in a multi-year effort to create the information needed to maintain viable fisheries in a warming world ocean. Projects are underway to improve stock assessments, modeling, and surveys, and to understand the vulnerabilities of coastal communities to climate change.
One of these projects looks at today’s cod in a warming Gulf of Maine through the lens of a similar time more than 300 years ago, when there was rapid ocean warming after the “little ice age” of the 1500s. Researchers are using fish parts gathered from a recent archaeological excavation of the Smuttynose Island fish station.
The fish parts date from 1640 to 1708, when the Smuttynose fish station was most active. The best-represented years are about 1640 to 1660. This was a time of intense harvest in the developing fishery during rapid ocean warming that is similar to what is happening in the Gulf of Maine today.
Examining these old fish parts may reveal how cod responded to intense fishing and warming in the 17th century. It will help us better project outcomes for Atlantic cod in the future.
